Abstract
We report the first demonstration of a high average power tabletop soft x-ray laser. An average laser output power of was generated at 46.9 nm in Ne-like Ar using a very compact tabletop discharge. The spatially coherent average power emitted by this 26.5 eV laser is comparable to that generated at this photon energy in a similar bandwidth by a third-generation synchrotron beam line. Lasing was obtained at a repetition rate of 7 Hz with an average output energy of by exciting a plasma column in a ceramic capillary with a fast current pulse. This very compact high-repetition-rate laser source makes intense short-wavelength coherent radiation accessible to a wide variety of new applications.
